I don't dare take time for a full response here. Let me just point out that
I think that "aoristic present" is an *Aktionsart* category, not an
aspectual one. Arguments for such a creature always point to the nature of
the action so described--and that is *not* what aspect is all about--but
that IS what Aktionsart is intended to describe.
